Everyone who has graduated

Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted to at least one of them.

The statements above, if true, best support which of the following conclusions?

A: Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.
B: If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.
C: If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.
D: At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.
E: If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.

OA: C

Stimulus mentioned "Ivy League universities" but option mentioned "Ivy-League school." Is it acceptable?

A is incorrect because they would have accepted only if they had applied. It is not mentioned that whether they have applied.
B in incorrect because they might have attended TopNotch High School for very short period but actually they have graduated from some other school.
C is correct because of the word "possible"
D not really. It possible only if If IQ is higher than 150.
E what about E?

E misses specifying top notch high school. It only suggests 'high school'
Success is a journey.....enjoy every moment of it

Applying does not guarantee attending.

The logical problem in E is that students might have applied and selected but they are not attending instead they are at some other university.

Very confusing answer choices. I hope that such questions do not appear in the real GMAT. Too many assumptions to be made in answer 3.

E is not valid because someone with an IQ of 150 could have applied and been accepted to an ivy-league school, but chose not to attend.
